Amblyopia is commonly called Lazy Eye. It begins to develop early in life; in fact, it results when one eye is slower to develop the ability to see than the other. This can occur if the vision in one eye from early childhood is less clear than in the other. Anisometropia is when one eye is much more nearsighted, farsighted, or has more astigmatism than the other, so that one eye sees more clearly than the other. The blurry eye becomes the lazy eye. Amblyopia also occurs when the eyes don’t work together because of Strabismus – when one eye turns in (crossed eyes or Esotropia), or when one eye turns out relative to the other (wall-eyed or Exotropia). Regardless of the cause early diagnosis and treatment is the only way to prevent amblyopia. THIS IS ONE IMPORTANT REASON WHY YOUR CHILD’S EYES SHOULD BE EXAMINED BEFORE THE AGE OF 3 YEARS.
